CLEC3B and hepatocellular carcinoma: In view of CLEC3B was a secreted protein [28, 29], thus we collected the supernatants from HCC cells with CLEC3B level changes, and found that the supernatant from CLEC3Bhigh HCC cells (3B) inhibited migration (Additional file 6: Figure S4B and S4C) and invasion of HCC cells (Additional file 6: Figure S4D).
